Skip Tracing / Off Market Deals

Hello I am looking for this communities wisdom.

When it comes to cold calling to cultivate off market deals I heard skip tracing llc is a possibility.

I heard that batchskiptracing has very high connect rate.

How do you guys cold call for off market deals?

Do you call straight to the office off a list from axeldata or do you take extra steps like skip tracing and trying to connect with them directly?
